Harry Potter Question

I just lent out my copies of the Harry Potter books to my middle sister. Tonight I am making a birthday cake for my nephew, child of my younger sister. He wants the Hogwart’s motto on the cake but I can’t remember the Latin. In English it’s

“Never tickle a sleeping dragon”

Can someone please help me out if you have the books? I was silly to lend them before doing the cake.

“Draco Dormiens Nunquam Titillandus”

Thank you jayjay ! You have saved this aunt a lot of trouble!
